Fruit Fly Key Identification:
Fruit Fly Size: (3mm)
Fruit flies are small about 1/8-inch in length including the wings.
Fruit Fly Key Identification:
A key identifying character is its bright red eyes.
The Fruit fly is about one third the size of the filth or house fly.
Color:
Body color is usually a light yellow to tan color. Just because you may
see a small fly or gnat type flying around in the kitchen, do not
assume it is coming from the drains. Check all possible breeding
sources to help identify the fly. Using a drain cleaner like DF 5000
would only work in they are breeding in the drains.
Understanding
the different breeding sources for the different flies will help you in
identifying and managing the respective flies. The other flies that are
found around drains are: Fruit Flies, Drain Flies and Sphaerocierid
Flies.
Breeding Sources of Drain Flies, Fruit Flies, Phorid Flies and Sphaerocerid Flies:
Drain flies: breed in drains, sewers, septic tanks and soil that has been contaminated with sewage.
Fruit
flies: can be spotted around fresh fruits/vegtables, rotting fruits and
vegetables, drains, garbage and damp organic materials
Phorid
Flies : are found in sewage contaminated soil, garbage, drains, human
cadavers, rotting vegetables and fruit, garbage as well as damp organic
materials
Sphaerocerid Flies: may be found in manure, damp organic material, drains, rotting fruits and vegetables and garbage
Fruit Fly : Biology and Habits
Fruit
flies comprise several different species belonging to the genus
Drosophila. The most common species encountered in homes and other
structures is D.melanogaster. Fruit flies are also identified as pomace
flies or vinegar flies. These pests can be found throughout the world,
in homes, food processing plants, warehouses, grocery stores, wineries,
restaurants and other structures.
Populations tend to be greatest in late summer and early fall as they infest fruits during the harvest season.
The fruit fly is among the smallest flies found in homes.
With the end of the summer season, many homeowners often encounter
fruit flies in and about their kitchens and near garbage storage areas.
Fruit
flies are generally found hovering around decaying vegetation and
overripe fruit. The fruit fly is most often found hovering around
overly ripe fruit. Fermenting materials, such as leftover beer or soft
drinks, also are a favorite food of fruit flies. Fruit flies are often
found in the kitchen, especially when vegetable or fruit materials are
present after major home canning efforts.
Occasionally,
pomace flies, similar in appearance to fruit flies, may infest the
home. The source of a pomace fly problem is often standing water like a
forgotten mop pail or an open sewer drain.
Because it frequents such unsanitary areas, it could potentially carry disease-causing bacteria onto food products.
Like
all flies, the fruit fly develops by complete metamorphosis. Eggs are
laid near or on top of attractants (fermenting materials) such as
beverages, decaying fruit and vegetable matter, garbage or slime in
drains. The fruit fly is attracted to any area where moisture has
accumulated including mops and wet rags. The larvae emerge from the
eggs and feed near the surface of the fermenting material for 5-6 days.
This
surface-feeding characteristic of the fruit fly larvae is significant
in that damaged or over-ripened portions of fruits and vegetables can
be cut away without having to discard the remainder for fear of
retaining any developing larvae. However eating the larvae can cause
intestinal discomfort and diarrhea. For this reason, health
professionals and sanitarians are concerned when fruit flies are found
infesting facilities where food is prepared, processed, or served.
Newly-emerged
fruit fly adults are attracted to lights, but egg laying females will
not leave fermenting materials. The fruit fly larvae then crawl to
drier areas of the food source or even out of the food source to
pupate. Under ideal conditions, the life cycle of the fruit fly, from
egg to adult can be completed in as little as eight days. Life cycle
from egg to adult is approximately 10 days. Recommended Control and
Treatment for Fruit Flies :
Exclusion and Sanitation, Insecticides, Traps, and Aerosols
1. Exclusion and Sanitation:
Sanitation is the first measure of defense, even though there are
various traps and sprays that are used to kill fruit flies, it is
necessary to eliminate the source in order to eliminate them.
The key to controlling these fruit fly infestations is to locate and eliminate their breeding sources.
Fruit
Fly Inspection: Look first for fruit fly sources in areas where
vegetables or fruits are stored outside refrigeration. Also look for
fruit fly sources in garbage cans , under appliances, and recycling
bins. When searching for fruit fly breeding sources, remember that the
larva can only survive in decaying organic matter that is moist.
All
stages of a fruit fly infestations depend on organic debris to complete
the complete fruit fly cylcle. Whenever possible, food and materials on
which fruit flies can lay their eggs must be removed, destroyed, as a
breeding medium, or isolated from the egg-laying adult.
Killing adult fruit flies will reduce infestation, but elimination of fruit fly breeding areas is necessary for good management.
A space spray such as
V One Pyrethrum
(Pyrethrin spray) can be used as a quick kill, reducing populations of flying insects.
Garbage cans and dumpsters should have tight-fitting lids and be cleaned regularly.
Drainage will often aid control, getting rid of extra moisture.
Openings of buildings should be tightly screened with screen.
The
fruit fly larvae may feed on the sides of the drain and in the drain
trap if there is an accumulation of organic debris there. You can check
it by placing some tape over the opening (leave some opening for air
flow). If you find these flies stuck to the tape, you have discovered
the source.
Pouring bleach down the drain is not effective.
A bacterial digester like DF 5000 or Invade Bio Gel may be used to break up the organic debris.
Gentrol
Aerosol is an aerosol insect growth regulator to use to kill fruit fly
eggs and discourage immature fruit fly development. Gentrol can be
applied into drains, under appliances, floor mats, around plants,
dumpsters, etc.
Re-grouting tiles to prevent water seepage into walls will stop fruit
fly breeding in those sites. If found in rotting vegetable matter, the
source should be destroyed.
Clean dirty garbage containers, wet lint under the washing machine, and
even standing water in containers under houseplant pots. Outside the
home, inspect air conditioners, bird baths, shallow stagnant pools of
water and sewage treatment facilities upwind as the fruit fly will
travel with the wind.
2. Insecticides for Fruit Fly Control: Residual and Contract
DEMON
WP or
Cyper WP are wettable powders, mixed with water to spray exterior
surfaces where fruit flies would land, sprayed once a month.
We also carry fogging material and professional fogger equipment:
